Seems reasonable, to be honest. I probably get a little more than that per day, but I'm nowhere near some of the goofy levels I've seen /fit/ recommend. I've never been down with the 1-2 grams/lb body weight broscience that so many /fit/izens parrot. Seriously, does downing 4 scoops of whey powder and eating 2 whole chickens a day seem like it would be sustainable in the long-term? No fucking shit you're going to have health problems down the road.

However, >>32640671 also has a point. Exercise isn't taken into account at all. There are only a few variables being studied, which is good for an academic paper, since you get more robust results, but unhelpful for us. In this study, people in good shape who exercise several times a week and happen to have high-protein diets are being lumped in with people who never exercise and just eat lots of meat.
